Question about ARRAYWRITE

[circuitpro]

I've been looking at this all day, and it just doesn't work:

'PIC18F6722
OSC 40
ARRAYSIZE  CON  20
DJAM      CON     %01110111
ACK       CON     $06 
COMMAND   VAR     BYTE[20]
MESSAGE   VAR     BYTE[20]

LOOP1:
ARRAYWRITE MESSAGE,[HEX ACK," ",BIN DJAM]
ARRAYREAD MESSAGE, [COMMAND]
DEBUG STR COMMAND,10,13                                                     
ARRAYWRITE MESSAGE,[REP 0\ARRAYSIZE]
PAUSE 1000
GOTO LOOP1

OUTPUT:
61110111

If I just say "HEX ACK" it produces 61110111 (no space as I specified). If I try to use "HEX2 ACK", it doesn't show the first value OR the space, just the binary number! I need to write some rather complicated structured messages and store them, but I've found that

1) IN NO CASE will ARRAYWRITE write more than two items... (if there is more, they just don't show). The exact same structure prints fine using DEBUG.

For example: ARRAYWRITE MESSAGE, ["DJ_TMR",DEC X,":",DEC DJ_TMR[X]] will only show the first two values... DJ_TMR, and DEC X - nothing further.

2) ARRAYWRITE won't work with indexed variables.

All efforts done in PBP 2.60A. If anyone can tell me what I'm doing wrong, I would be most grateful!
